specs2 - how to swallow exceptions

I am using specs2 as my test framework. I want to simulate a use case in which actionA return a failing future. Like this:

  val actionA = mock[ActionA]
  val actionB = new ActionB(actionA)
  actionA.doSomthing(x) returns Future.failed(new Exception("bla"))
  try {
    Await.result(actionB.doSomthing(request), 1 seconds)
  }catch {
    case e: Exception => println("exception caught: " + e);
  }

The problem is that my test exit with this exception if I am not catching it, doesn't specs2 have a nicer way to swallow exceptions? Is there a better way to test such scenario?

Thanks!
